UNITED 1.S' TE$- ATEN OF E- vi I AUTOMATIC 'rnnm PIPE connnc rnn enn Application filed'June, 19, 1929, Serial No. 372L187, Renewed February 17, 1 93.2.

This invention relates to improvementsin automatic train p1pe connecters', and more' particularly to means for removing defective gaskets between the faces of connecterheads 5 while such heads remain-coupled. Theinvention is an improvement on the construction shown in my co-pending application Serial #357,853 filed April 24th,1929, and one object is to simplify the .construction. and

' eliminate all movable parts in the locking arrangement for anchoring theconduit removably in place either at the center of the con? pling head as showmorat' either end thereof;

In the drawing Figure 1 is asectional plan 1 5 view of my improvement. In this view fa part of the coupling head is shown;

Figure 2 is a sectional sideview of meta,

struction shown in Figure 1. In this view a part of theconduit G is brokenaway, and 9 Figure 3 is a front sectional view on the line 3'-3 of Figure 2.7 a y r i A 7 It will be understood that any desired type of coupling head, whether pin and funnel or the wing type, may be used with my improve- .25 ment. I illustrate a coupling head Aof the wing type.. It will also be understood that;

thecarrier or member B of my improvement may be secured to the coupl ng head n any desired manner, and that 1t is also a carri er or p 39 support'for the conduit G. as well as for the coupling head A, and that it may be attached to the head at the center or either end thereof.

In the present embodiment of my invention I provide the coupling head with ashank 10 3.5 into which I press or otherwise secure the forward hollow 'end or chamber 11 of the mem- 7 her B. However, such forward end of the member maybe riveted or bolted to-the head along the general lines of my co-pending ap 9 'plication Serial #418,233 filedQctober 20th,

- The member B includesapair of rearward ly extending spaced straps'12, arrangedto span or extend through the connecter bracket 7 (not shown). The straps. may of course be elim nated and a single stem' or projection, on other means, provided for mounting the wmember B on the bracket. Into the hollow forward end of the member, I removably Q mount the tubular conduit the forward ,muchjas the weight andresilieneefof of which extends through the coupling the memberB with a" suitable anchor lug 16' which preferably lies in the-vertical plane and extends-transversely of the member and 59 ,7 j .isprovided with an inclinedguiding face 16*, Figure 3. This lug isformedi'rintegral with the; member; but it may be made'separately thereof, and it is slotted at 17 Figure 3, to

receive theprojection 18 which extends rear 5 wardly away from the conduit C, and is pref. erably formed integral therewith. The rear P of the projection rests and ismovablein I the seat or undercut portion 20 ofthelug 1'6;

A transversely extending hookor fi iger 21 is -79. formed by the aforesaid undercut, and the projection 18 is held beneath' this finger and in sa d:seat,bythepressure fluid carried, and '1 by the hose 15,]as' islatermorefully pointed 7 b t I A wall or abutment 22 extends trans- 7 verselyofthe memb-erB andties the straps; 1.2 together. Upon" its front face'Iprovide this wan with-a slightly inclined machined bear ingsurface or seat23againstwhich the ma-f ".1 chlnedrear end or face ofthe pro ection 18 rests. said face being angledvtom ate with the f bearing23.- To prevent theconduitslippingforward out ofthe} chamber 1 1, the conduit is 1 curved quite closely.aroundthe point of' the' 1 J memberB,Figural. v

When it, is desiredtorreniove'the conduit from thegse'rvice' posit-ion shown in Figure 1,

the rear endaofthe conduit is swungjtrans versely of the member andfthe'projection 18 forced laterally todisengage .it'froni the hook ,9

I p tion will replace the conduit. I It-fwill' beun- V V v der stood of course that the inclined surface 23, and the mating similar surface on -tjhe rear end ofthe portion 19,; facilitate insertion andremovaljofzthe' conduit G, and also that inas ber train pipe hose tends always to draw .the conduit C downwardlyxand towards the: hose, 'thatthe'projection 18, will always be thereby held in locked'engagcment, with the p lug-1 6, asshown'especially'in Figures-land 3;

The pressure ofthe fluid carried tends always .to straighten' the rubber -ho's e,15v with theresuit that when the connectersare coupled, and
